So I’m following a tutorial online which uses RF transmission of data.
Here are mine attached.
The Rx unit
I have 4 pins and 2 are labelled data. Does it matter which one I pick?
The Tx unit
Mine has Gnd, Vcc and then data.
Well I just noticed their fritzig diagram is different from their actual connections:
I’ll just follow my labels on my circuit boards. It’s just that last night I tried it and found out the transmit code hangs right before initializing the Tx unit.
